[Chris Gotstein]

There is going to be a lot, as this will be carrying 90% of our ISP 
customers traffic.  It's the aggregation point for all our customers 
connecting through the core to our internet routers.  Would i be better 
off using a separate aggregation switch, then dumping into the 6506? 
Was trying to save money by using the 6506.
